I defend pornography as an important aspect of freedom of expression, which is essential for autonomy, self-development, the growth of knowledge and human flourishing. I rebut the allegations that pornography depraves and corrupts, degrades women, is harmful to children, exposes third parties to risk of offence or assault, and violates women ’s civil rights and liberties. I contend that suppressing pornography would have a range of unintended evil consequences, including loss of beneficial technology, creeping censorship, black markets, corruption and extensive social costs
